DIY RAM: Backyard Cleanroom Builds Memory From Scratch

A severe global memory shortage, exacerbated by AI data center demands, has led to skyrocketing RAM prices. Manufacturers are prioritizing high-bandwidth memory for large corporations, leaving consumers with few options. While new semiconductor fabrication capacity is not expected until at least 2027, some enthusiasts are exploring unconventional solutions.

One such innovator, YouTube creator Dr. Semiconductor, has established a class 100 semiconductor clean room in his backyard shed. This extreme setup allows him to construct RAM memory cells from the ground up, starting with silicon wafers. The meticulous fabrication process involves separating chips, coating them with oxide, using UV light and etching to create channels, doping the silicon for conductivity, and finally spraying with aluminum.
